At 10x10 a hitori grid holds a hundred numbers and enough repetition that scanning alone will not get you far. The puzzles on this page are built for solvers who already know the patterns and want a longer sitting: you will typically clear the obvious triples in the first two minutes, then spend the rest of the puzzle proving cells white by contradiction — shade this, and a corner is cut off; shade that, and two blacks end up adjacent. It is the most satisfying size for exactly that reason.

One 10x10 hitori grid per page, laid out to keep cells comfortably large despite the grid size, with digits set for legibility once a neighboring cell is filled in. Each puzzle has a matching answer page showing the completed shading. Black and white throughout, one puzzle per US Letter page, printer friendly with no heavy background fills.

Frequently asked questions

What is the fastest way into a 10x10 hitori?
Sweep every row and column once, marking any number that appears three or more times in the same line. In a line of ten, a number appearing three times means at least two of them must be shaded, and since shaded cells cannot touch, their positions are often forced. That single sweep usually places a third of the shading.
Does the white region have to be connected diagonally too?
No — connectivity is measured through shared edges only. Two white cells touching at a corner are not connected unless there is a horizontal or vertical white path between them. Shaded cells, by contrast, are allowed to touch at corners, and in finished grids they usually do, forming diagonal staircases.
Can I use these for a puzzle club or a substitute lesson?
Yes. Print as many copies as you need for your own classroom or group. One 10x10 comfortably fills a class period for solvers who already know the rules, and printing the answer page separately lets you check work without handing the solution out.
Is hitori related to sudoku?
Only loosely. Both were popularized by the Japanese publisher Nikoli and both forbid repeated numbers in a line, but sudoku asks you to place digits and hitori asks you to remove them. Solvers often find hitori a refreshing change precisely because the mechanic is inverted.
